Clients like Morgans Hotel Group (MHG) and Vikram Chatwal Hotels (VCH) don't come to Mark Zeff for G-rated interior design. They want sexy hotels for adults who work smart and play hard, and they demand design solutions that do the same. Zeff Design isn't about the clichéd fantasy of space opera furnishings or bordello Baroque. There's a sense of authentic history in each project: references to the verticality and intricacy of Gothic design in Night; an antique barber's chair and the hand-made collage installation at The Smith; the restored frescoes in Social Hollywood. "People feel better surrounded by things with a sense of history. I've yet to find a modern experience that makes me feel warm and fuzzy," he says.
